[0022] As a kind of preferred technical scheme, the preparation method of described modified lyocell fiber and modified cotton fiber comprises the steps:

[0023] 1) The lyocell fiber and cotton fiber are processed through opening, impurity removal and carding;

[0024] 2) Prepare a modification solution, immerse the treated lyocell fiber and cotton fiber in the modification solution, wash and dry with clean water after immersion, the immersion time is 2-3h, and the temperature is 30-40°C.

[0025] As a preferred technical solution, the modification solution in step 2) is an amino polysiloxane solution, and the methyl siloxane is mixed with the catalyst, the reaction temperature is 120°C, and the reaction time is 1.5h. A coupling agent was added under vacuum to continue the reaction, and an end-capping agent was added in the later stage of the reaction to prepare an aminopolysiloxane solution. The reaction time was 4 hours, and the reaction pressure was 0.02 MPa.

Abstract

The invention provides a fabric with excellent performance and application of the fabric in the field of clothes. Raw materials comprise lyocell fibers and cotton fibers, wherein the ratio of the lyocell fibers is 60-70%, and the ratio of the cotton fibers is 30-35%. The prepared fabric is natural in gloss, smooth in hand feeling, good in moisture permeability and air permeability, the color fastness is larger than or equal to the third level, the decomposable carcinogenic aromatic amine dye is smaller than or equal to 20 mg / kg, and the fabric is extremely excellent in performance and can be widely applied to the field of clothes.

Description

technical field [0001] The invention relates to the field of clothing, in particular to a fabric with excellent performance and its application in the field of clothing. Background technique [0002] Lyocell fiber is a new type of man-made fiber that has many advantages over other fibers and is a regenerated cellulose fiber. It not only has the comfort, moisture absorption and air permeability of cotton fiber, but also has the silky feeling and luster of real silk, as well as good spinnability; it has been widely used in the textile field and is an ideal fiber for clothing. Lyocell fibers are often dyed with synthetic dyes, but the prepared fabrics contain high levels of decomposable and carcinogenic aromatic amine dyes, which are highly harmful to human health. But when lyocell fibers are dyed with natural dyes, the affinity between natural dyes and lyocell fibers is weak, the reactivity is poor, the dyeing rate is not high, and the color fastness is low. [0003] Cotton ...
